Abstract

The invention discloses a cooling device for laser welding. The cooling device comprises a light-transmitting pipe, a hollow, a water inlet pipe, a water outlet pipe and an air inlet pipe. The light-transmitting pipe is composed of a light-transmitting pipe shell. A coil pipe is arranged outside the light-transmitting pipe shell. The coil pipe is a half pipe, the lower portion of the coil pipe isconnected with a water inlet pipe, and the upper portion of the coil pipe is connected with a water outlet pipe. The cavity serves as an annular air channel, and is formed by a cavity outer wall and acavity inner wall. The upper portion of the cavity outer wall is connected with the air inlet pipe. The cavity is closely connected with the coil pipe, and an isolating screen is arranged on the lower portion of the cavity. The cavity serves as the annular air channel, and an air curtain is formed around a laser welding nozzle, and dust is prevented from entering a laser beam channel to contaminate a lens. Meanwhile, a welded workpiece can be purged, and the problem of weld porosity caused due to the fact that a workpiece is not cleared up is avoided; and in cooperation coil pipe cooling, thesituation that the temperature rises in the transmission process of laser beams in a laser channel is avoided, and consequently the laser mode changes, and the welding quality is influenced is avoided.

Description

technical field [0001] The invention belongs to the field of laser welding equipment, in particular to a cooling device for laser welding. Background technique [0002] Laser welding is a new type of welding method, mainly aimed at the welding of thin-walled materials and precision parts. The weld seam is smooth and beautiful, the quality of the weld seam is high, there is no air hole, it can be precisely controlled, the focusing spot is small, the positioning accuracy is high, and it is easy to realize. Automation, so laser welding machines have been widely used in many fields. [0003] Traditional laser welding has always had problems that are difficult to solve, that is, after a period of welding, the welding quality will deteriorate, and in severe cases, the welding work will not be able to be carried out. There are three main reasons for this: First, dust enters the laser channel during the welding process , pollute the lens, reduce the reflectivity, and affect the las...
